Abstract: Systems, methods, and computer program products for determining the location of, and for communicating with a mobile device. An intelligent fixture transmits a first signal having a first spatial resolution and a second signal having a second spatial resolution. The spatial resolutions may be determined by a radiation pattern of the antenna broadcasting the signal. The mobile device receives at least one of the first and second signals, and determines an approximate location based thereon. An approximate location based on the first signal may be more accurate than an approximate location based on the second signal due to the different spatial resolutions of the signals. Location specific information may be transmitted to the mobile device based on the approximate location. The intelligent fixture may use an antenna having one spatial resolution for transmitting and receiving communication signals, and another antenna having a different spatial resolution for broadcasting beacon signals.
